FREQUENTLY ASKED QUESTIONS ABOUT 750450-001
What is the difference between 750450-001, 727258-B21 and 815983-001?
750450-001, the number on this page, is an HPE spare part number — the number used for service replacement and printed on the physical battery. 727258-B21 is the option kit number, the salable number used when the battery is ordered as a configurable option. 815983-001 is another spare number for the same battery. All three identify the same physical 96W Megacell Smart Storage Battery with 145mm cable.
Why do I see other numbers cross-referenced for this battery?
Beyond the spare and option numbers, this family also carries two OEM model numbers and one additional spare part number, all listed in the cross-reference block on this page. An OEM model number identifies the unit as built by the manufacturer, before HPE assigns service or option identifiers. Any of these numbers may appear in service records or on labels, and all point to the same physical battery.
Which servers does this battery support?
This 96W Megacell Smart Storage Battery is listed for HPE Gen9 platforms: DL20 Gen9, DL60 Gen9, DL80 Gen9, DL120 Gen9, DL160 Gen9, DL180 Gen9, DL380 Gen9, DL388 Gen9, DL560 Gen9, ML110 Gen9, ML150 Gen9, and ML350 Gen9. Cable routing differs by chassis, so verify that your server uses the 145mm cable variant rather than a longer cable before installing.
Does the 145mm cable length matter?
Yes. The Smart Storage Battery connects to the system board or backplane through a dedicated power cable, and HPE ships this battery in more than one cable length to suit different chassis layouts. This part is the 145mm (5.7 inch) version. If your server was built with a longer cable, that variant carries a different part number, and the 145mm cable may not reach the connector.
What arrives when I order 750450-001?
You receive the 96W Megacell Smart Storage Battery with its 145mm power cable, the same physical assembly identified by the option kit and the other spare numbers for this product. The battery is the flash-backed write cache backup power source for supported Gen9 servers; it does not include a storage controller, cache module, or mounting hardware unless your chassis reuses the existing bracket.
